MOLD FOR CASTING PRINTERS INKING-ROLLERS.

SPECIFICATION forming part of Letters Patent No. 725,357, dated April 14, 1903.

Application filed February 12, 1902. Serial No. 93,722. (No model.) I

To ctZZ whom it may concern.-

Be it known that I, J OSEPH H. Osooon, a citizen of the United States, residing at Peabody, in the county of Essex and State of Massachusetts, have invented certain newand useful Improvements in Molds forOasting Printers Inking-Rollers; and I do hereby declare the following to be'a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it ap'pertains to makeand use the same.

Myinvention consists of an improved mold for casting printers inking-rollers, and relatesto novel features in the foot and tube and to the connection of the foot with devices for letting on or cutting off the supply of the composition.

In the drawings serving to illustratemy invention, Figure 1 shows a central vertical section of the device; Fig. 2, a transverse section through the line 1 1 of Fig. 1; and Fig.

.3, a similar transverse section, but when the tube has been turned partly around. Fig. 4 shows a partial elevation; Fig. 5, a similar central section showing the lower end of the tube surrounding instead of being Within the foot or base, and Fig. 6 a-transverse section in the line 5 5 ofFig. 5.

The improved mold has two main or leading features-viz., A its foot, and B the tube.

Referring to Figs. 1 ande, the foot A is stationary or non-revoluble, and its bottom is closed and has in it a central conical depression 1), into which the ordinary roller stock or core may by its own weight truly center itself at its lower end, and at the upper end, as shown in Fig. 1, this stock or core The footA being stationary or non-revoluble does not shift or turn around or pull its supply-pipe or connections, and therefore avoids all risk of loosening or deranging them. These roller stocks or cores belong to the printing-presses and are placed in the mold to be cast upon, but form no part of the mold itself.

As shown in Figs. 1, 2, 3, the foot A has a projection a upon one side, but has no opening at its bottom. Through this projection a tapering hole a is cut,as shown. Intothis nipple is adapted to be connected directly or by means of a tube, as indicated at E, with any air-tight tank or vessehas will be underthe nipple D. This hole, as shown in Figs.

hole a conical nipple D fits closely. This 1, 2, 3, is of as large diameter as the inner end of the conical nipple D, passing through the projection a of the foot A. When this hole 12 near the end of the tube B is opposite or in coincidence with the hole 01 in the foot A, there is a clear passage into the tube for the liquid composition. a

nipple D and its adjacent parts being in position, asshown in Fig. 1, the cock used to control the flow is then opened. The melted composition is thus allowed to flow into the tube of'the mold until it becomes filled. Then the supply is stopped by turning a cockto' shut off further supply of the composition.

In order to keep the composition from flowing out from the filled or charged mold when this mold is to be removed from its connection with the supply tankor vessel, the tube B is turned or revolved upon its foot A'sufliciently to bring the hole 17 away from the hole d in the foot and against the solid part of the foot. This closes the tube perfectly.

A slight variation, though having the same principle, object, and mode of action, is illustrated in Figs. 4:, 5, 6. In this variation or style the tube 13 fits the exterior of the foot A instead of its interior, this foot being preferably turned off or reduced externally, as shown, for the purpose, as seen in Fig. 5. The manner of closing the mold after filling it is the same as already stated, by simply revolving the tube to the right or to the left, so that its inlet-passage b shall be turned away from the inlet tube or nipple D*, and thus close it. This nipple-tube D" has near its inner end a flange (1 Around this tube fits a ring F, adapted to be moved easily, and it is provided at its front end at 1 with a cam or section of a screw-thread. This cam or thread 1 is interrupted or cut away in one portion, so as to allow it to pass or slide under or beyond the head of a screw it, fixed in the tube B. Then the ring is turned. The earn 1 engages the inner side of the screwhead it and forces this ring up to the flange d of nipple tube D thus crowding the flange tightly around the hole (1 in the tube B. As will be seen in Fig. 5, the hole (I in footAis,as shown,countersunk around it, and is thus adapted to receive the inner end and also the annular flange d of the nipple-tube D*, and thus the end of this tube fits tightly against said flange when it is crowded or pushed by the turning action of the cam 1, bearing upon the fixed screw-head h.

In my invention the tube B is not screwed or fixed in any way at its bottom, but is simply deposited in or on its foot A, as stated, and which alone supports it vertically. It

can therefore be removed from its foot or base by merely lifting it out, and in order to aline its lateral passage b with the hole or passage (2 in the foot A the tube B is merely to be turned to cause these passages to coincide,

and in order to close 12 it is simply needed to turn its passage (Z away from 11 I claim- 1. A mold for casting printersrollers, composed of a tube readily removable from its stationary foot or base and having an inletpassage near its lower end, and adapted to be freely turned within such base, the latter having a lateral inlet-passage for admitting the composition to such mold, all substantially as shown and described.

2. A mold for casting printers rollers, composed of a simple tube freely revoluble on and removable from its supporting-base and having an inlet-passage near its lower end, combined with a base stationary or non-revoluble relatively to such tube, said base having a lateral inlet for admitting the composition to such mold, all substantially as shown and described.

3. In combination with a readily revoluble and removable tube, having an inlet-passage near its lower end, the stationary or nonrevoluble base for supporting said tube and having the bottom of the base permanently closed and provided therein with a conical recess as and for the purpose set forth.

4. In combination with the base A closed at its bottom, the tube B axially turnable on said base, and having an inlet as described, the flanged nipple-tube D*, 01 ring F and its cam 1, and the fixed screw-head h, as and for the purpose set forth.

In testimony whereof I have affixed my signature in presence of two witnesses.
